Harrow.



UNITED STATES `l'o all whom, it may concern: i Be it known that I, J oHNM. KILLOUGH, a citizen of the United States, residing at Waco, in thecounty of McLennan and State of Texas, have invented new and usefulImprovements p lin Harrows, of which the following is a speci-`lication. My invention relates to improvements in harrows of the clodcrushing or pulverizing ltype g and it consists in a certain peculiar'conf j struction the novelty, utility, and advantages of which will befully understood from the j following description and claims when takeny i in conjunction with the accompanying drawings, in which- V i j fFigure lis a plan View of my improved harrow with the driveris seat inbroken lines and `the seat-support in section. Fig.` 2 is a View, partlyin side elevation and. partly in longitudinal section, taken on thebroken line 2 2 l ofwFig. 1. Figs. 3 and 4 are detail sections E g takenin the planes indicated by the broken l. lines 31 3 and it 4f,respectively, of Fig. l; and j Fig. 5 is a perspective view of one ofthe links of the barrow-frame. l Similar letters of reference designatecorresponding parts in all of the several views of `the drawings. f Inthe preferred embodiment of my invention the harrow-frame is made up offorward Y and rear side bars A, which are made of steel or othersuitable metal and are preferably I- p shaped in transverse section, andlinks B, which are also ofsteel or other suitable metal and, bypreference, of I shape in cross-sec- 1 tion. The side bars are providedat their unlder sides adjacent to their ends with apertured lugs a andare also preferably provided j at about their middles withvertically-disy 1 posed apertures Z1 for the reception of bolts c,`which serve to connect cross-timbers C to `the side bars, as best shownin Fig. l. The links B, like the side bars, have apertured lugs d attheir under sidesV and at or adjacent to their ends, and also havebolt-holes e ,adjacent to their middles to receive bolts f, j whichconnect a cross-timber D thereto, as shown. The cross-timbers C D do notform j essential elements of the frame; but I prefer I to employ them,since they serve to support PATENT OFFICE.

HARRow.

SPECIFICATION forming part of Lei-.ters Patent No. 681,230, dated August2v, 1901'. 4 Appiiitiion nei April' 25, 1901. serai No. 57,470. dit mansame on the harrow, and one of them also' serves for the connection ofthe support of the drivers seat F, as shown in Figs. l and 2. Inaddition to the lugs ci the forward side bars A have forward aperturedextensions g for the connection of a draft-bail; but these extensionsare also not essential, since the draft animal or animals may beconnected to the harrow in any suitable manner without departing fromthe scope of my invention.

G G are shafts interposed between the side bars A of the frame. Theshafts G are pref erably of gas-pipe for the sake of cheapness.Thewforward and rear shafts Gare journaled in lugs 0i of the side bars Aand extend laterally outward from said side bars and have toothed wheelsI xed on their extended poras shown, or other suitable means, while theintermediate shafts G are journaled in and extend through the coincidentaperturedl lugs of the side bars and links and serve to con- The saidintermediate shafts G are provided at the outer sides of the links Bwith collars j, -which are fixed on them by setescrews t' or other`suitable means and have for their purpose to hold the links on theshafts.

`It is obvious that when desired the forward and rear shafts G might beprovided at their ends with collars j in lieu of the toothed wheels Iand that the intermediate shafts G might be provided with toothed WheelsI in lieu of the collars 7' without departing from Vthe scope of myinvention.

Fixed on the shafts G by set-screws t" or other suitable means aretoothed wheels I', calculated to crush or pulverize the clods of earthover which they pass. These toothed Wheels are arranged about six inchesapart on the shafts, and the toothed wheels on each shaft are arrangedin alinement with. the spaces between the toothed wheels of the nextadjacent shaft or shafts, this in order to enable the rear toothedwheels to engage clods of earth that pass between the forward toothedwheels and insure the thorough crushing or pulverizing of all of theearth in the path of the harrow. In will also be observed that the teethof the several toothed wheels all weight when it is necessary to imposethe point in different directions,.so that some of tions by adiametrically-disposed set-screw-t',

nect the same together in a hinged manner. l

the teeth will be in the soil all the time and the wheeled shaftsenabled to roll in a regular manner.

Spacing-collars I2, interposed between the side bars A and links B andthe toothed wheels I', adjacent thereto, and other spacing-collars I3,interposed between said bars and links and the outer toothed Wheels Iwhen the latter are employed, serve to hold the shafts Gr againstendwise play or casual movement.

It will be readily observed from the foregoing that while the toothedwheels fixed on shafts, as described, are calculated to thoroughly crushor pulverize clods of earth in their paths and level and render thesurface firm they are not liable to catch into grass or other trash orhang on stones, roots, and the like, and consequently render theharrowvery easy of draft, also that when desired the harrow may beincreased in width by simply using longer shafts G with a greater numberof toothed wheels thereon.

It will further be observed from the foregoing that the several shaftsbearing toothed wheels are linked together, and consequently the raisingof one shaft bya stone, stump, or other obstruction in the path of theharrow will not affect the other shafts, which willremain on the groundand to their work.

The construction described is further advantageous, since the shafts Gmay be made of gas-pipe or other cheap material and t-he side f bars Aand links B of steel or. other metal calculated to withstand friction,and when the shafts are worn their position in the side bars and linksmay be readily changed. The manner described of connecting the wheeledshafts to the side bars A and links B is also advantageous, because ofthe facility with l which the parts may be connected and disconnected,and in this connection it will be noticed that when one ofthe shafts isre- .f moved from the frame one or all of its ythe present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and side bars, transverseshafts journaled in the outer transverse apertures of the side bars andextending outwardly beyond said bars, transverse shafts journaled in thealined aperturesof the sidebarsaudlinks andextending outwardly beyondthe same, teeth on the portions of the shafts between the side bars andlinks, and detachable means on the extended portions of the shafts forholding the side bars and links thereon.

2. The harrow described comprising the forward and rear side bars havingtransversely-disposed apertures, links arranged parallel to said sidebars and having transverselydisposed apertures arranged coincident withthe inner apertures of the side bars, transverse shafts journaled in theouter apertures of the side bars and extending outwardly beyond thesame, transverse shafts journaled in the alined apertures of the sidebars and links and extending outwardly beyond the same; said shaftsbeing tubular, toothed wheels detachably secured on the shaft atintervals between the side bars and the links of the shafts for securingthe side bars and v links thereon.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
